摘要：
An electrical heating device for medical equipment is provided. The electrical heating device includes a conducting body forming a channel therethrough for fluid travel, a base dielectric layer disposed on the conducting body, a heater surrounding the base dielectric layer and the conducting body, a top dielectric layer disposed on the heater, and a protection housing that is preformed and that defines a cavity to receive the top dielectric layer and the heater in the cavity. The base dielectric layer and the top dielectric layer jointly enclose the heater. At least one of the base dielectric layer and the top dielectric layer has a radial portion at a side of the heater such that the radial portion surrounds a portion of the base layer dielectric that is sandwiched between the heater and the conducting body and no portion of the heater is exposed from the base dielectric layer and the top dielectric layer. The protection housing defines side pieces that are in direct contact with the conducting body
